Overview of K976MS – 976nm High Power Fiber-Coupled Diode Laser

The K976MS is a multi-mode high power fiber-coupled 976 nm laser diode from BWT.  This easy to integrate OEM laser diode module utilizes specially designed micro-optics to transform the asymmetric beam out of the laser chip improving the beam quality to couple the laser into small core fiber optics providing up to 330 watts of power and unprecedented brightness.  This high-efficiency laser module comes equipped with a  0.22 NA, 106.5-micron core.  The volume Bragg grating stabilized external laser diode cavity design of the K976MS not only offers wavelength stability and a linewidth less than 1 nm, but it also reduces the overall power consumption and thermal load by limiting the number of modes lasing at a giving time.
